What closer evolutionary relationship do current genomic evidence and mitochondrial DNA analyses suggest yaks share?
Answer
A closer evolutionary relationship with bison (*Bison bison* and *Bison bonasus*)
Current genomic evidence, derived from mitochondrial DNA analyses, suggests a significant evolutionary finding: yaks may share a closer relationship with bison species, such as *Bison bison* and *Bison bonasus*, than with other members currently categorized within the genus *Bos*. This potential relationship introduces complexity to the traditional family portrait, as it implies that the genus *Bos*, as currently structured, risks becoming paraphyletic, meaning it would not encompass all the descendants of its common ancestor shared with the bison lineage.
